Nanga bwanji ngati kuyankha kwaubongo ku mphotho kumachitika ngakhale kulibe mphotho? Kodi sichingakhale chodetsa nkhawa kwambiri kwa anthu omwe ali ndi vuto lotchova juga komanso mitundu ina yazovuta, monga zomwe zimakhudzana ndi kudya? Electroencephalography idagwiritsidwa ntchito kuti ifufuze kuthekera kumeneku pogwiritsa ntchito mayankho okhudzidwa ndi zochitika zina zodziwika bwino zokhudzana ndi zochitika (ERPs) zokhudzana ndi kukonza mphotho. Tinayesa kuyerekezera-kuti ma ERP omwe amapatsidwa mphothoyo amatha kuchitika ngakhale kulibe mphotho yowoneka bwino komanso ngati zomwe akuyembekeza zikuchitika. Njira yodziwika yankho la P300 inali yofunika kwambiri, ndipo adayesedwa mwa omwe sanadzitchova njuga omwe sanamaliza maphunziro awo pantchito yokhudzana ndi mayesero oyeserera a mayankho abwino kapena olakwika omwe ali ndi mayesero atatu-80, 50, kapena 20% mayankho abwino. Chotsitsimutsa cha mayankho (F1) chidatsata kuyankha pakati pazotsatira ziwiri zomwe zingachitike (kuwina / kutayika kwathunthu), kenako chotsitsimutsa chachiwiri (F2) chidaperekedwa kuti zitsimikizire kuti akuti 'win' kapena 'kutayika' (kuwina / kutayika kodziwikiratu). Zotsatira zinawulula kuti matalikidwe a P300 mu data yotsekedwa ndi F1 (kuwongolera kwathunthu) inali yayikulu (yowonjezera) pafupifupi pazotsatira zamayankho zomwe zidasokonekera kukhala zochepa kuposa momwe amayembekezera. Zotsatirazi zimanenedwa pambuyo pochulukitsa nthawi yogwira ntchito (mayesero amtsogolo), ngakhale ambiri mwa omwe sanatengepo gawo sanadziwe bwino za zomwe tingathe kuchita. Zotsatira zowonekera mu data yotsekedwa ndi F2, palibe tanthauzo kapena tanthauzo lalikulu lomwe lawoneka. Zotsatira izi zikuwonetsa kukhalapo kwa njira zomwe zingayankhidwe bwino zomwe sizigwira ntchito momveka bwino komanso ndi zovuta zina zomwe sizikutanthauza kuwina kapena kutayika, ndipo sizikugwirizana ndi mphotho zowoneka. Chifukwa chake, zikuwoneka kuti pali mawonekedwe osazindikirika (timatcha 'osasunthika') ogwirizana ndi zomwe zimachitika mkati mwa zopambana / zotayika (pakalibe mphotho zenizeni kapena zotayika) zomwe zitha kuwerengedwa muzochitika zamaubongo. Kufunika kotheka pazomwe zapezazi kumafotokozedwera malinga ndi tanthauzo la kutchova juga.
